Certain VisualShader nodes (constants) contain a selectable, blank bar above the editor part

Issue description

If you click on it once it stays selected until you reload the editor (or in some cases toggle the preview).

There seems to be a context menu registered for this, but the entries are disfunctional:

(I'd assume that clicking on "Copy Value" on a TransformConstant and then clicking on "Paste Value" on another TransformConstant or Transform property editor is its intended use case, but that does nothing - just like "Copy Property Path" (which does not even make sense to me here).

Edit:
This is probably because some VisualShader ***Constant nodes use the same property editors which are used in the inspector:

So the blank bar usually contains the property's name, but since this is no property here it remains empty. I think it should either be editable to give the constant a name or removed/replaced completely.

Steps to reproduce

Create a VisualShader resource and add e.g. a TransformConstant or Vector2/3/4Constant.

It seems Nodes like VisualShaderNodeVec3Parameter suffers this problem too if enable it's default value, they use the same property editors which are used in the inspector. And for this case, the blank bar should be removed since it's already has a name field.

However after some digging, I find that it's non trivial to remove this label :(
